Low CRI lighting

If LED lamps are so great, why is there so much terrible LED lighting? Are dull colours just the price you pay for lower bills?

The answer to these questions is "Colour Rendering Index".

In most LED lamps it's simply too low. At Well-lit, all our LED lamps have CRI values of 93 or above. So you can replace your halogen and incandescent lamps without losing quality of light. (And change those poor quality LEDs for something rather better.)
